Attacks are defined as passive and active. A passive attack is an attempt to understand or create use of data from the system without influencing system resources; whereas an active attack is an attempt to change system resources or influence their operation.Passive Attacks − Passive attacks are in the feature of eavesdropping on, or observation of, transmissions. The objective of the opponent is to access data that is being transmitted. There are two method of passive attacks are release of message contents and traffic analysis.The release of message contents is simply learn. A telephone chat, an electronic mail message, and ...

LastIndex() is a built-in function of strings package in Golang. This function is used to check the index of the last occurrence of a specified substring in a given original string. If the substring is found in the given string, then it returns its index position, starting from 0; otherwise it returns "-1".SyntaxThe syntax of LastIndex() is −func LastIndex(str, substr string) intWhere, str is the string inside which we need to search, andsubstr is the substring that we want to search inside the str.Example 1Let us consider the following example −package main import ( "fmt" "strings" ) func ...

The OSI security architecture provides the managers responsible for the security of an organization in describing the necessity for security. The OSI security architecture was introduced as an ‘international standard’ which allow the computer and communication dealer produce the products that have security characteristics depends on this architecture.The OSI security architecture has a structure description of services and structure for supporting security to the organization’s data. The OSI security architecture targets on security attacks, structure, and services.These can be represented concisely as follows −Security attack − Security attack is any action that deal the security of data owned by an ...

A security model is a computer model which can be used to analyze and enforce security policies. It does not require some previous formation and it can be organized on the access right model or inspecting computing model or computation model.A security model is a mechanism in which a security policy is produced. The development of this security policy is regulate to a definite setting or example of a policy.A security policy depends upon authentication, but construct within the confines of a security model. For instance, it is designing a security model depends upon authentication and authorization. It can consider ... Read More

Application Gateway is a type of firewall that supports application-level control over network traffic. Application gateways can be used to deny access to the resources of private networks to distrusted clients over the web.An application gateway is an application program that runs on a firewall system between two networks. When a client program creates a link to a destination service, it connects to an application gateway, or proxy. The client then compromise with the proxy server to interact with the destination service. In effect, the proxy creates the connection with the destination behind the firewall and acts on behalf of ... Read More
Application-level GatewayAn application gateway or application level gateway (ALG) is a firewall proxy which offers network security. It filters incoming node traffic to certain specifications which define that only transmitted network application information is filtered. Such network applications such as File Transfer Protocol (FTP), Telnet, Real Time Streaming Protocol (RTSP) and BitTorrent.An application layer gateway also known as an application proxy gateway. It can perform a several functions at the application layer of an infrastructure, generally known as layer 7 in the OSI model. These functions can include address and port translation, resource allocation, software response control, and synchronization of ... Read More
